Sometimes it is possible for DXers to send reception reports to broadcasters, not ask for a QSL, and to provide technical information about their signals. In this case, a report was sent to the English language section of Vatican Radio regarding an issue with an annoying whistle that was happening on their Arabic Language broadcast. They forwarded the message to Vatican Radio’s technical section. I am not sure if they were already aware of the problem, or if this message made them aware. But it goes to show that DXers can alert broadcasters when there is a problem.
